CORDING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 410,618, datedSeptember 10, 1889. Application filed July 22, 1881. Serial No. 38,404.(MedeL) Patented in England March 11, 1882,N0.1,192-

To whom, it may concern.-

Be it known that I, EDWIN J. TOOF, a citizen of the United States, and aresident of the city of New Haven, in the State of Connecticut, haveinvented certain new and useful Improvements in Cording Attachments forSewing-Machines, of which the following is a specification.

My invention relates to thatclass of. attachments adapted for use incombination with sewinganachines; and it consists of a cording-guideadapted to direct cord and braid to the needle to be sewed upon fabricfor trim min g, the. The channel-way which forms the guide for the cordis so constructed as to admit the cord through a flexible opening at itsside without passing its end through its entire length; and it alsoconsists in the peculiar construction of the attachment and theattachment-holder or presser-foot at their point of connection, wherebythe said attachment may be held rigidly in position without the use ofscrews, &c., and for which I have obtained Letters Patent in GreatBritain, dated March 11, 1882, No. 1,192, the object of the open-sidedflexible channel-way being to produce the proper tension to the cordwhile being fed through the channel or guide, and to permit quickadjustment and placing of the cord in position while the machine is inoperation.

Referring to the drawings, Figure 1 represents a perspective view of myimproved corder attached to a presser-foot. Fig. 2 represents a bottomview of the same, showing the bottom or lower part of the deflectedchannel-way. Fig. 3 represents a section of the foot and tongue of theattachment in position, showing the slit, recesses, and counterparts.

A is a presser-footserving as a holder, constructed to rigidly supportthe guide in position without the use of screws; and to this end,therefore, the holder is provided with a transverse slit in one side ofthe lower portion of the shank thereof at its junction and parallel withthe foot, as clearly shown in Fig. 3. A recess and an aperture areprovided in the foot portion to assist, in connection with said slit, insecuring the two parts of the device together, the guide having a shankof construction complemental thereto, as hereinafter described, beingheld detachably upon said presser-foot or holder, as will be more fullyexplained hereinafter.

The guide to be attached to said. holder is provided with a tongue B,having two small projections a and Z) on its under side to engage therecess and aperture, respectively, in the said foot. The projections areformed in this instance by deflecting the metal outwardly, as shown inFig. 3.

The method of attaching the guide to the holder is as follows: Theoperator should take the guide in the right hand, enter the projection1), formed upon the short end of the tongue, as shown, into the openingprovided for it at the heel of the foot of the holder, and then by aswinging movement of the guide toward the left enter the same into theslit in the shank A and slightly spring the tongue upward. The secondprojection is then made to enter the recess provided for it at or nearthe toe of said foot of the holder, into which it springs by theelasticity of the tongue B, where it is securely held for operation.

0 represents the bow or bridge part of the attachment, one end of whichis secured to the said tongue B. The said bow or bridge forms thesupport for the parts which form the lengthened channel-way or guideproper, which channel-way consists of the arm 0, the said arm being acontinuation of the bow C, and another piece of metal (represented at D)provided with a groove or channel, formed in this instance by bending ordepressing one edge of the metal into a groove larger at one end andgradually narrowing at the opposite or delivery end. The piece D is thenriveted to the arm 0, although it is obvious that it may be soldered orotherwise secured thereon. When the piece D is secured to the arm 0,that edge or side provided With the groove is placed even with the outeredge of the arm O, leaving an opening along the front edge, forming amouth widest at the end near the bow, and gradually narrowing toward thepoint of delivery adjacent the foot when in position, as shown inFig. 1. This opening is formed by the edge of the piece D being bent ordepressed, forming a groove or channel-way, as hereinbefore described,and the outer edge of the groove not being bent or brought back to thesame level with the body of the piece. The edge is below the level ofthe body of the said piece D to a greater degree near the mouth of thegroove, and gradually tapers toward the delivery end till it is quite onthe same level with the body of the piece D, thus forming the saidopening in the lengthened channel-way or guide proper.

By the construction of the parts and the thinness of the metal (ascombined) an elasticity of the opening is secured, which permits ofready and easy application of the cord to its position. The easiestmanner of placing the cord in position is to enter the cord at thewidest opening of the mouthabout, say, tWo inches (more or less) fromthe endand then by the end draw it forward and into the entire openinginto and'through the delivery end, and then draw back, as may berequired, leaving enough projecting from the delivery end for the needleto act upon, so that it may be fed automatically.

Having thus set forth my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is

The improvement in cording attachments for sewing-machines hereindescribed, the same consisting in the combination, with the presser-footor holder having a transverse slit in one side of the lower portion ofthe shank at its junction with the foot and parallel therewith, andhaving a recess at the front and an aperture at the rear in the uppersurface of said foot portion, of a cordguide having a guidingchannel-way therein and provided with a spring-metal shank havingprojections complemental to the recess and aperture in the foot, wherebythe said shank may be sprung Within the transverse slit in thepresser-foot or holder and firmly seated by the engagement of the saidprojections upon the shank, with the recess and opening at the front andrear portions, respectively,
